Description 
</td> 
<td class=apiTableRightDescr>Computes and applies the mass and inertia properties for a convex shape (or convex compound shape), based on a density value. If call this function while the simulation is running, you will have to call <a href="simResetDynamicObject.htm">sim.resetDynamicObject</a> upon the object, for the changes to take effect. See also <a href="simGetShapeMassAndInertia.htm">sim.getShapeMassAndInertia</a> and <a href="simConvexDecompose.htm">sim.convexDecompose</a>.</td>
